We are looking into alternative gear systems for a saltwater spinning reel. The gear ratio would be close to 4 to 1 with the smaller tooth gear driving the larger.
Considerations (in order of importance):
1. smoothness
2. durability in a marine environment
3. be able to adjust backlash
As a bit of background, most spinning reel gear systems use a die-cast bevel spiral gear system. In this way, shims can easily adjust the backlash for variations in gears and the gear housing. The problem with die-cast gears is that they are subject to both wear and corrosion.
We are now looking into various treatments to the die-cast gear that may help the above problems, but failing that, a die-cast gear or a sintered gear (due to roughness)will not work for this reel.
Machine-cutting bevel spiral gears is too costly for our application.
Any thoughts would be greatly appreciated!
